Embodiment
The embodiment of the present application provides a kind of method and system of screening duplicated entity data.
In order to make those skilled in the art person understand better the technical scheme in the application, below in conjunction with the accompanying drawing in the embodiment of the present application, technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment is only the application's part embodiment, rather than whole embodiment.Embodiment based in the application, those of ordinary skills, not making under the creative work prerequisite the every other embodiment obtained, should belong to the scope of protection of the invention.
The system architecture that the application relates to can as shown in Figure 1, comprise server and database.
Below introduce the application's screening duplicated entity data embodiment of the method, Fig. 2 shows the flow process of the method embodiment, as shown in Figure 2:
S201: server obtains solid data to be screened.
The entity here can be embodied as shop, and the shop entity of take in follow-up describes as example.
The data of shop entity to be screened comprise the data of the attributes such as shop title, address, shop and shop telephone number.These data can be used as shop relatively to be screened whether with database in the foundation that repeats of existing shop.
S202: the solid data of scheduled volume entity title relatively one by one in the solid data that server will be to be screened and database, this one by one comparison procedure comprise:
Utilizing the participle dictionary of preset different parts of speech to treat the entity title of screening in entity title and database carries out participle and determines part of speech; Wherein, the entity title participle in database, determine that part of speech can fulfil ahead of schedule;
To insert respectively predetermined template through the trade name to be screened of the also definite part of speech of participle and the entity title in database;
The whether identical scoring that obtains the comparison of entity title of word by entity trade name corresponding part of speech in described template in trade name relatively to be screened and database.
S203: server is by relatively scoring and preassigned assign to judge whether solid data described to be screened and the solid data in database repeat.
Below specifically introduce entity title implementation relatively in S202, it is that the title of entity to be screened and the entity title in database are compared, and this comparison procedure comprises the step shown in Fig. 4:
S401: utilize the participle dictionary of preset different parts of speech to treat the entity title of screening in entity title and database and carry out participle and determine part of speech.
By the participle dictionary, trade name is carried out to participle, by each word in trade name by the predefine dictionary under it, and, according to the part of speech of this predefine dictionary, be the word mark part of speech in trade name (set different parts of speech in the example here and be labeled as S, P, C, O, N, X etc.).
For example, " Xi'an China the moral food and drink De Keshi of company limited high-new dining room " such trade name can obtain " Xi'an _ S Hua De _ X food and drink company limited _ O De Keshi _ N high-new _ S dining room _ O " such result by the trade name word segmentation processing.
For the entity title is carried out to participle, and can identify each participle identity property (place, mechanism, industry etc.) after participle, need minute dictionary of pre-save by parts of speech classification, such as the region dictionary, the place dictionary, mechanism's dictionary, industry dictionary, orientation dictionary, main trade name, minute trade name etc.In order to improve the participle accuracy rate, add brand and divide dictionary, collected the shop brand name in shop in this dictionary, for example, McDonald, KFC, the brand name in the shops such as outer husband's family.
In the example of the present embodiment, entity title (as the shop title) is done to following dimension cutting:
Table 2
Below respectively each minute top dictionary introduced:
The region dictionary: what wherein include is the whole of China each province, city, town, township, the title in village.Also can retain in addition a participle of removing regional predicate in this dictionary, for example, can include Zhejiang Province and Zhejiang, Hangzhou and Hangzhou, Xianoshan City and Xiaoshan, Huaxi Village and West China simultaneously.Economize, city, town, ,Qi, village, township also is embodied in this dictionary as the region participle.This dictionary is relatively fixing can great changes have taken place.
The place dictionary: wherein include Zhong Yi street, place, ,Lu, Jie, lane, community, inner, the Nong, main road, Village, market, square, mansion, factory building, shop, crossing, the place noun of lane ending, street, ,Lu, Jie, lane, community, inner, the Nong, main road, Village, market, square, mansion, factory building, shop, crossing, lane itself is also the participle in this dictionary.
Mechanism's dictionary: all mechanisms word is divided into to 8 classifications.Respectively integrated service, amusement and recreation, shopping square, food and drink cuisines, living information, trip/tourism, atural object, company/factory.In addition, for the classification in shop, have fuzzy region, a shop likely not only belongs to the living information classification but also belong to trip/tourism classification exactly.In this case mechanism's word classification is adopted the principle of preferential coupling, as shown in Figure 5.Shown in Fig. 5, mechanism's word classification priority level is arranged from high to low according to the direction of arrow indication.For example, there is mechanism's participle " Internet bar " both likely to appear in the amusement and recreation classification, also likely appear in living information.Shown in Fig. 5 priority, the limited level of amusement and recreation is higher than the priority of living information, and therefore, " Internet bar " should belong to mechanism's participle of amusement and recreation class.The application does not do restriction to the sorting technique of mechanism and the preferential matching principle of mechanism's classification.
The industry dictionary: be similar to shop, branch, ,Yuan, pavilion, home office, an independently dictionary can be put in the public participle of a plurality of categorys of employment.For example: branch, building materials company Xiaoshan, east, Hangzhou, see branch, upper city with knowing to distinguish the flavor of, " branch " this word is arranged in trade name, but " branch " both belonged to company/factory, the food and drink of belonging to was arranged, so " branch " income therein in dictionary, must can not be indexed to " branch " this word in an independent file dictionary without industry mechanism.The word that is similar to " branch " also has, ,Dui, building, shop, and city ,Zuo, society, OK, shop, meeting, hall, chamber, paving etc.
Main trade name dictionary, branch thesaurus: in order to improve the participle accuracy rate, add brand and divide dictionary, collected the shop brand name in all shops of public praise net (www.koubei.com) in this storehouse, for example, McDonald, KFC, the brand name in outer husband's family shop.
Word in dictionary has following characteristics, and the brand word is less than two words, or is greater than not including of six words.Can not exist with shop industry or mechanism's dictionary in the participle that existed.
Here part of speech is made to introduction:
N brand word
O mechanism word
C industry word
S region word
P place word
The word that X does not separate
SN branch name brand word
PS region word
FN cum rights participle
For FN, certain XX bath center, hotel for example, wherein the part of speech of XX is exactly FN, then certain XX of company parking lot for example, and the part of speech of XX wherein is exactly FN.
Utilize above-mentioned participle dictionary to treat the entity title of screening in entity title and database and carry out participle and determine part of speech, specifically can carry out as follows:
A1: utilize the participle dictionary of preset different parts of speech to treat the entity title of screening in entity title and database and carry out forward participle and reverse participle.
The forward participle is, according to dictionary, trade name is from left to right carried out to participle, and oppositely participle is, according to dictionary, trade name is carried out to participle from right to left.For example, by trade name, be that " result that ”De shop, potato restaurant space flight bridge shop obtains according to the forward participle is " potato _ restaurant _ boat _ overline bridge _ shop ", and the result obtained according to reverse participle is " potato _ restaurant _ space flight _ bridge _ shop "." potato restaurant space flight bridge shop " carries out respectively forward participle and vocabulary that oppositely participle obtains as shown in following table 3 and table 4:

Table 4. is word segmentation result oppositely
Here participle adopts short-circuiting method, and each word only has a part of speech.So-called short-circuiting method, be exactly at first step participle, in dictionary, searches the word of coupling, if found the word of coupling just to exit, and then turns to the coupling of next word, so just can guarantee that the part of speech that separates word according to dictionary does not have ambiguity at once.
Maximum coupling number of words can be set as 10, and the word that from left to right this is to the maximum to 10 words carries out participle.Disposable this 10 words that obtain, in dictionary, whether these 10 words of checking are words, if, the word mark part of speech and the end that these 10 words are formed, if not, from left to right get 9 words, whether checking can form a word, if can in dictionary, find the word of coupling through checking, finish.If not former word string being reduced to a word, then mated in dictionary, by that analogy until only remain next word in word string.
By top example, obvious, obtained different word segmentation result by forward participle and reverse participle, so just need a selection adopt the treatment scheme of which result as last word segmentation result.This flow process is exactly next step disambiguation that need to illustrate.
A2: forward participle and the vocabulary that oppositely participle obtains are carried out to the disambiguation processing to obtain unique word segmentation result.
Here the qi that disappears is processed and is comprised following three rules:
Rule I: the word that marks off non-X part of speech of take is the main qi that disappeared.
For example: Shanghai _ S southern station _ P restaurant _ O, upper _ X Hainan _ S station _ X restaurant _ O, wherein the ambiguity word is " Shanghai _ S southern station _ P ", " upper _ X Hainan _ S station _ X ", at this moment getting first word that separates non-X part of speech is that " Shanghai _ S southern station _ P " is correct result.
Rule II: the minimum word of the X part of speech of take is the main qi that disappeared.As the result that " cuisines shop " carried out to forward participle and reverse participle according to A1 is respectively " cuisines _ C shop _ O ", " U.S. _ X eats shop _ O ", and in the part of speech that the former separates " cuisines _ C shop _ O ", the word of X part of speech is minimum, according to regular II, with " cuisines _ C shop _ O ", be as the criterion.
Rule III: take reverse word segmentation result as correct result.

The word segmentation result that table 5. is disappeared after qi is processed and obtains
In addition, the participle priority can be set as follows: brand (N), and mechanism (O), industry (C), without industry mechanism (O), place (P), region (S).For example, if it is " little shop " that a word is arranged in dictionary in the dictionary of brand storehouse and mechanism database, a shop is now just in time arranged " the little shop of cuisines ", result after participle is " the little shop _ N of cuisines _ C " so, rather than " the little shop _ O of cuisines _ C ", because the priority of the word in the priority ratio dictionary O dictionary in the N dictionary is high.
Can also comprise A3: the monosyllabic word processing procedure.
May there is the part of None-identified after disambiguation, just need to carry out the monosyllabic word processing when the length of the X part of speech part that can not identify only has a word, to identify its part of speech.For example:
If right monosyllabic word is catering industry suffix word, left word is industry word or brand word, and left word and right word merge, and part of speech is as the criterion with left word.
As above example, word segmentation result be " space flight C_ bridge X_ shop O ", will become a new word " space flight bridge shop _ C " with left word and the merging of right word after " bridge " disambiguation of centre
If right word is catering industry prefix word, right back word (first word after right word) is industry word or brand word, and right word and right back word are merged, and with right back word part of speech, is as the criterion.
If right word is mechanism's suffix word, left word is mechanism's word or brand word, and by a left side, right word merges, with left word part of speech for Whom.
If right word is mechanism's prefix word, right back word is mechanism or brand part of speech, and right word and right back word merge, and with right back word part of speech, are as the criterion.
S402: will insert respectively predetermined template through the trade name to be screened of the also definite part of speech of participle and the entity title in database.
For example, the form of template can be as follows, front and back sequentially the sort number of this part of speech of numeral wherein in this template:
0:N 1:S 2:P 3:PS 4:C (describing main shop industry) 5:O 6:SN (describing the industry of SN) 7:C 8:O9:FN
By the word segmentation result obtained, aforementioned through participle and determine the trade name to be screened of part of speech and the entity title in database, according to part of speech, insert among template.
For example, shop to be selected is respectively " assistant is stepped on the international beauty treatment of Coronis foundation shop " and " assistant is stepped on Coronis ".
" assistant is stepped on the international beauty treatment of Coronis foundation shop " participle is divided into: the 0-N|1-C|2-SN|3-O(brand | industry | and branch | mechanism)
" assistant is stepped on Coronis " participle is divided into: the 0-N(brand)
By these two after the shop title of selecting is inserted template result be:
Table 6
S403: by the whether identical scoring that obtains the comparison of entity title of word of entity trade name corresponding part of speech in described template in trade name relatively to be screened and database.
Whether the word by entity trade name corresponding part of speech in described template in trade name relatively to be screened and database is identical, can obtain the scoring relatively of entity title.For example:
Trade name to be screened and the entity trade name of inserting template are compared, and concrete, each position compares, and the 1st, identical, the 0th, different; Every comparative result is left in a scale-of-two array, by the scale-of-two array be converted into decimal number as a comparison the part of result return.
The mark shop is each minute trade name in comparison procedure in twos, main industry, and whether the main frame word-building is equal state, and whether what is called is equal state, and within two minutes, whether whether trade name be all empty or be all that data are arranged.
Trade name comparison appraisal result is that the comparative result according to each part of speech of trade name decides, and comparison rule is as follows:
As for how obtaining the scoring relatively of entity title, only provide some exemplary examples here, for example:
I: if the unequal words of trade name main body in shop directly return to 0;
II: if comparative result is 511(511, by Binary Conversion, get, conversion regime is with reference to hereinafter discussing), and the comparative result on 4 positions is all 1, trade name judgment result is that fully equally so, returns to 100;
Otherwise:
The result of each bit comparison and 16 is carried out and operation, and result is not equal to 16, returns to 75; Or,
The result of each bit comparison and 32 carry out with operation or with 64 carry out and operation, if any more than one result, be 0, return to 75; Or,
In each bit comparison result, the state (SN) of minute trade name is returned as 0, returns to 75; Or,
The result of each bit comparison and 1 is carried out and operation, if result is 0, returns to 2; Or,
Each bit comparison with 8 carry out and operation, if result is 0, return to 2; Or,
If the result of each bit comparison is greater than 0, return to 75; Or,
Other situation returns to 0.
According to above-mentioned rule, each participle part of speech in table 6 is compared, can obtain following table 7, wherein y means identical:
N |
S |
P |
PS |
C |

SN |
C |

Table 7
Each part of speech comparative result is as implied above.
If two identical participle comparative results of part of speech are y weights are 1, and score will be removed top brand word N.Staying 9 bit comparison results is 111111111, must be divided into 1 * 2
9+ 1 * 2
8+ 1 * 2
7+ 1 * 2
6+ 1 * 2
5+ 1 * 2
4+ 1 * 2
3+ 1 * 2
2+ 1 * 2+1 * 2
0=511.Final score is 511, illustrates that trade name is fully equal, returns to 100.
Again for example, remain the selection shop as follows:
The shop title |
The address, shop |
Telephone number |
The crystal moon design centre |
No. 217, Wen Yilu (Hangzhou Normal College opposite slightly to the right or left) |
88828282 |
The crystal moon is sent out skill salon |
No. 217, Wen Yilu |
88828282 |
Table 8
In above form, at first two shops compare trade name are carried out to participle:
" crystal moon design centre " participle is divided into: the 1-N|2-O(brand | mechanism)
" the crystal moon is sent out skill salon " participle is divided into: the 1-N|2-O(brand | mechanism)
According to the trade name comparison rule, each participle part of speech after participle is compared as following table:
N |
S |
P |
PS |
C |

Table 9
According to comparative result master trade name, mechanism is unequal, and comparative result is 495, with 2
5Doing with the result operated is 0, so trade name is unequal.
But, for the example in table 8, according to address, shop and telephone number, clearly, these two entities of " crystal moon design centre " and " the crystal moon is sent out skill salon " are for repeating entity.For this situation, on the basis of relatively marking in the entity title, can also comprise: determine according to entity title comparative result and telephone number whether solid data repeats, or determine according to entity title comparative result and address whether solid data repeats.In example as top table 8, although the scoring of title comparative result for not repeating, reference phone numbers is identical, can determine that result is repetition.Again or, although the scoring of title comparative result for not repeating, reference address is identical, can determine that result is repetition.
In S401, can also comprise:
S401 ': will carry out respectively pattern match through trade name to be screened and the entity title in database of participle definite part of speech, the pattern rules that find this rule to mate from the pattern rules file, thereby by part of speech on the mark of word segmentation in title.
After S401 processes, also have our None-identified of part word in trade name, and the word that is designated N may be shop master's trade name, may be also that trade name is divided in shop, and minute trade name and main trade name role in the title comparison process of shop are different.Like this, just word segmentation result need to be matched to different patterns.Such as, the rule of " Xi'an _ S Hua De _ X food and drink company limited _ OD De Keshi _ N high-new _ S dining room _ OD " is S-X-O-N-S-O, in obtaining result, rule is S-X-O-N-S-O, most result can be regarded as a brand by second X, the 4th N regards as SN branch title, so, can be 0-S|1-N|2-O|3-SN|4-S|5-O by the S-X-O-N-S-O rule match, can enumerate 400 nearly through these rules of statistics, account for more than 90% of GREV.
Below some common rule that exist:
Wherein, X means not determine the participle of part of speech.
More than to have intercepted a certain section rule in the rule file, the form of every rule be take equal sign as being divided into left and right two parts, the left side be word segmentation result (the part of speech sign order that has marked part of speech after the trade name participle, sequencing according to participle in trade name is arranged), right-hand component is the mode of rule that left side word segmentation result is matched to according to the principle of probability statistics.
The process that generates this part of rule file is as follows:
B1: word-dividing mode participle and the mark part of speech for trade name that will have all Yellow Pages shop now.
B2: by word segmentation result according to parts of speech classification.
For example, what by all word segmentation result attributes, be " X-O-O " assigns in a group, and adds up the number in every group.
B3: reject the low frequency group that number is no more than and do not make subsequent treatment.Because these shop titles do not have general character thereby do not have reference value.
Can also introduce manually-operated, rely on artificial experience, which part of speech is " X " part in the judgement word segmentation result should be designated as.Also likely, the participle of former " C " before this, " O ", " P " part of speech should be likely other parts of speech according to judgement.
The effect of rule match is exactly by likely error of original machine judgement, and by realizing artificial screening verification create-rule file, the false judgment of when robotization is processed, effectively correcting machine, therefore can improve the correctness of final participle judgement.
In this treatment step is carried out, when obtaining a rule, just from the pattern rules file, search the pattern rules that this rule is mated, just can be by part of speech on the mark of word segmentation in trade name after finding.
Described embodiment of the method can also comprise:
S204: server will be judged as unduplicated solid data and be added in described database.
In S202, take shop is example as entity, the existing Yellow Page of storage shop data can adopt the postgresql database, because postgresql supports full-text index, and support distributed type assemblies, due to these two advantages, can store existing shop data with the postgresql database in this step.Fig. 3 shows postgresql database cluster topology figure.Before carrying out the shop duplicate removal, at first need to deposit existing all Yellow Pages shop data in four data nodes, which back end is concrete shop data be kept on, is to formulate according to the hash algorithmic rule of reserving in advance, and rule is as follows:
Shop id is the guid of 32, get major key first, when primary value is 0~3 to be stored on the newkoubei node, when primary value is 4~7 to be stored on the datanode1 node, when primary value is that 8~b is stored on the datanode2 node, when primary value is that c~f is stored on the newkoubei node.
In S202, the solid data of scheduled volume in described database, can be all solid datas in database.Mean like this in S202 and need solid datas all in solid data to be screened and database is carried out to comparison one by one.
In addition, the solid data of scheduled volume in database, can be the part solid data in database, for example, in the present embodiment, provides the suspection solid data of this part solid data for screening from all solid datas of database.Mean like this, solid data that will be to be screened in S202 contrasts one by one with the suspection solid data filtered out.
Entity be take shop as example, and the part solid data is specially here suspects shop.Suspect shop, the full-text index mechanism based on the above-mentioned postgresql of utilization database is carried out the full text matched and searched, can find the shop data of all couplings.
In the system constructing process, can, by the shop data importing of all Yellow Pages in the distributed data base shown in Fig. 3, according to Data dissemination hash algorithm, all Yellow Pages shop data can be distributed in four data nodes of Fig. 3 fifty-fifty.
Can preserve the table in Yellow Page shop in each back end, the structure of table can be as follows:
Table 1
The data type of the indexcontent field in above form is the tsvector type, can be by shop title and address name by word segmentation processing in the system initialization process, generate using space character as the character string of demarcating the initialization value as the indexcontent field.
Search the flow process of suspecting shop and be divided into following steps:
The shop name in Yellow Page shop to be found is connected with space with a minute trade name, generates the participle string with the space boundary;
By participle string obtained above, with the indexcontent(inverted index type field in table 1) carry out matched and searched;
Merge the Query Result on each back end, generate and suspect shop Query Result set.For example four data nodes here.
Generate to suspect the shop query results, can mate and obtain according to participle string indexcontent in 1 on each back end.Detailed process can be: the inquiry string with space-separated at first generated by previous step and city, place, shop id(city) combination producing sql statement.For example, there is the name in a shop to be called " crystal moon design centre " obtains " the crystal moon _ N sends out skill _ X; design centre _ OB " result by after the trade name participle, then the participle attribute is removed, be assembled into " crystal moon design centre ", then assembling generates the sql statement:
With this sql statement, the data node is inquired about, the result set of generation is exactly that object of suspicion is repeated in next step shop needed.
The technical scheme provided from above the embodiment of the present application, server obtains solid data to be screened, server will be to be screened solid data and database in the solid data of scheduled volume the entity title is compared one by one and is marked, server assigns to judge that with preassigned solid data described to be screened and the solid data in database repeat by relatively marking, and can screen out efficiently the solid data of repetition.
